What you want to use for the light changes would be ClockMod.inc by Chris
Colefax.  I'm guessing you already went and got that.  All you do is declare a
'start_clock' and 'finish_clock' with a 'clock_type' ("S" might be good) then
include the clockmod.inc and use 'mclock' in place of 'clock'.
As Chris H. and David C. have suggested you will need to use 'media' since fog
isn't going to show light and shadow.

| Thanks to everyone who has helped me out so far with all my questions, and
| especially to Ken for guiding a relative newcomer to the newsgroup and to
| POV-Ray!
|
| This is something that i've been trying to do on my own for a few weeks now,
| but I just can't seem to get anywhere with it. Hopefully someone out there
| can help.
|
| Firstly I want to created a hollow sphere that is filled with small holes. I
| imagine it looking like it's been sprayed with gunfire.
|
| Next I want to place a light source inside the sphere so that the light
| shines out through the holes and creates narrow beams of light, perhaps
| making use of some mist or fog.
|
| I would also like to animate the scene with a camera flying around the
| object. It would also be useful if the light source could be switched off at
| the start of the animation and then about 1/3 of the way through the
| animation suddenly increase from a low glow to a really bright light.
|
| I know it's a lot to ask for and that there are many issues to consider, but
| i'd be really appreciative of any comments, source code or advise anyone
| has,
|
| Please e-mail any files to me if possible (or reply to this posting of
| course!)
|
| Thanks
| Paul
